@Sheil Yerbouti anu suggestion for apps which save battery life? My new phone barely makes it through the day.
You can skip step 1 of course. The rest should be ok.
Imo, the highest battery drainers are the screen and background app syncing along with Wi-Fi and GPS being enabled when not in use. So reduce brightness and screen timeout limit, turn off auto sync for apps that you don't use frequently, enable Wi-Fi, Bluetooth & GPS only when needed. That should help.
